  },
  &quot;conditions&quot;: [ # Output only. Status conditions describing the workstation configuration&#x27;s current state.
    { # The `Status` type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by [gRPC](https://github.com/grpc). Each `Status` message contains three pieces of data: error code, error message, and error details. You can find out more about this error model and how to work with it in the [API Design Guide](https://cloud.google.com/apis/design/errors).
      &quot;code&quot;: 42, # The status code, which should be an enum value of google.rpc.Code.
      &quot;details&quot;: [ # A list of messages that carry the error details. There is a common set of message types for APIs to use.

Encrypts resources of this workstation configuration using a customer-managed encryption key (CMEK). If specified, the boot disk of the Compute Engine instance and the persistent disk are encrypted using this encryption key. If this field is not set, the disks are encrypted using a generated key. Customer-managed encryption keys do not protect disk metadata. If the customer-managed encryption key is rotated, when the workstation instance is stopped, the system attempts to recreate the persistent disk with the new version of the key. Be sure to keep older versions of the key until the persistent disk is recreated. Otherwise, data on the persistent disk might be lost. If the encryption key is revoked, the workstation session automatically stops within 7 hours. Immutable after the workstation configuration is created.
    &quot;kmsKey&quot;: &quot;A String&quot;, # Immutable. The name of the Google Cloud KMS encryption key. For example, `&quot;projects/PROJECT_ID/locations/REGION/keyRings/KEY_RING/cryptoKeys/KEY_NAME&quot;`. The key must be in the same region as the workstation configuration.
    &quot;kmsKeyServiceAccount&quot;: &quot;A String&quot;, # Immutable. The service account to use with the specified KMS key. We recommend that you use a separate service account and follow KMS best practices.

When set to true, disables public IP addresses for VMs. If you disable public IP addresses, you must set up Private Google Access or Cloud NAT on your network. If you use Private Google Access and you use `private.googleapis.com` or `restricted.googleapis.com` for Container Registry and Artifact Registry, make sure that you set up DNS records for domains `*.gcr.io` and `*.pkg.dev`. Defaults to false (VMs have public IP addresses).

      &quot;enableNestedVirtualization&quot;: True or False, # Optional. Whether to enable nested virtualization on Cloud Workstations VMs created using this workstation configuration. Defaults to false. Nested virtualization lets you run virtual machine (VM) instances inside your workstation. Before enabling nested virtualization, consider the following important considerations. Cloud Workstations instances are subject to the [same restrictions as Compute Engine instances](https://cloud.google.com/compute/docs/instances/nested-virtualization/overview#restrictions): * **Organization policy**: projects, folders, or organizations may be restricted from creating nested VMs if the **Disable VM nested virtualization** constraint is enforced in the organization policy. For more information, see the Compute Engine section, [Checking whether nested virtualization is allowed](https://cloud.google.com/compute/docs/instances/nested-virtualization/managing-constraint#checking_whether_nested_virtualization_is_allowed). * **Performance**: nested VMs might experience a 10% or greater decrease in performance for workloads that are CPU-bound and possibly greater than a 10% decrease for workloads that are input/output bound. * **Machine Type**: nested virtualization can only be enabled on workstation configurations that specify a machine_type in the N1 or N2 machine series.
      &quot;machineType&quot;: &quot;A String&quot;, # Optional. The type of machine to use for VM instances—for example, `&quot;e2-standard-4&quot;`. For more information about machine types that Cloud Workstations supports, see the list of [available machine types](https://cloud.google.com/workstations/docs/available-machine-types).
      &quot;poolSize&quot;: 42, # Optional. The number of VMs that the system should keep idle so that new workstations can be started quickly for new users. Defaults to `0` in the API.

      &quot;reservationAffinity&quot;: { # ReservationAffinity is the configuration of the desired reservation from which instances can consume resources. # Optional. [ReservationAffinity](https://cloud.google.com/compute/docs/instances/reserving-zonal-resources) specifies a reservation that can be consumed to create VM instances. If SPECIFIC_RESERVATION is specified, Cloud Workstations will only create VMs in the zone where the reservation is located. This would affect availability since the service will no longer be resilient to zonal outages. If ANY_RESERVATION is specified, creating reservations in both zones that the config creates VMs in will ensure higher availability. **Important Considerations for Reservation Affinity:** * This feature is intended for advanced users and requires familiarity with Google Compute Engine reservations. * Using reservations incurs charges, regardless of utilization. * The resources in the pool will consume the specified reservation. Take this into account when setting the pool size.

When specified, be sure that the service account has `logging.logEntries.create` and `monitoring.timeSeries.create` permissions on the project so it can write logs out to Cloud Logging. If using a custom container image, the service account must have [Artifact Registry Reader](https://cloud.google.com/artifact-registry/docs/access-control#roles) permission to pull the specified image. If you as the administrator want to be able to `ssh` into the underlying VM, you need to set this value to a service account for which you have the `iam.serviceAccounts.actAs` permission. Conversely, if you don&#x27;t want anyone to be able to `ssh` into the underlying VM, use a service account where no one has that permission. If not set, VMs run with a service account provided by the Cloud Workstations service, and the image must be publicly accessible.

<div class="method">
    <code class="details" id="getIamPolicy">getIamPolicy(resource, options_requestedPolicyVersion=None, x__xgafv=None)</code>
  <pre>Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

Args:
  resource: string, REQUIRED: The resource for which the policy is being requested. See [Resource names](https://cloud.google.com/apis/design/resource_names) for the appropriate value for this field. (required)
  options_requestedPolicyVersion: integer, Optional. The maximum policy version that will be used to format the policy. Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected. Requests for policies with any conditional role bindings must specify version 3. Policies with no conditional role bindings may specify any valid value or leave the field unset. The policy in the response might use the policy version that you specified, or it might use a lower policy version. For example, if you specify version 3, but the policy has no conditional role bindings, the response uses version 1.

  An object of the form:

    { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { &quot;bindings&quot;: [ { &quot;role&quot;: &quot;roles/resourcemanager.organizationAdmin&quot;, &quot;members&quot;: [ &quot;user:mike@example.com&quot;, &quot;group:admins@example.com&quot;, &quot;domain:google.com&quot;, &quot;serviceAccount:my-project-id@appspot.gserviceaccount.com&quot; ] }, { &quot;role&quot;: &quot;roles/resourcemanager.organizationViewer&quot;, &quot;members&quot;: [ &quot;user:eve@example.com&quot; ], &quot;condition&quot;: { &quot;title&quot;: &quot;expirable access&quot;, &quot;description&quot;: &quot;Does not grant access after Sep 2020&quot;, &quot;expression&quot;: &quot;request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;)&quot;, } } ], &quot;etag&quot;: &quot;BwWWja0YfJA=&quot;, &quot;version&quot;: 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;) etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).

If you omit this field, then IAM allows you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost. If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

If ANY_RESERVATION is specified, creating reservations in both zones that the config creates VMs in will ensure higher availability. **Important Considerations for Reservation Affinity:** * This feature is intended for advanced users and requires familiarity with Google Compute Engine reservations. * Using reservations incurs charges, regardless of utilization. * The resources in the pool will consume the specified reservation. Take this into account when setting the pool size.

When specified, be sure that the service account has `logging.logEntries.create` and `monitoring.timeSeries.create` permissions on the project so it can write logs out to Cloud Logging. If using a custom container image, the service account must have [Artifact Registry Reader](https://cloud.google.com/artifact-registry/docs/access-control#roles) permission to pull the specified image. If you as the administrator want to be able to `ssh` into the underlying VM, you need to set this value to a service account for which you have the `iam.serviceAccounts.actAs` permission. Conversely, if you don&#x27;t want anyone to be able to `ssh` into the underlying VM, use a service account where no one has that permission. If not set, VMs run with a service account provided by the Cloud Workstations service, and the image must be publicly accessible.

  <pre>Sets the access control policy on the specified resource. Replaces any existing policy. Can return `NOT_FOUND`, `INVALID_ARGUMENT`, and `PERMISSION_DENIED` errors.

Args:
  resource: string, REQUIRED: The resource for which the policy is being specified. See [Resource names](https://cloud.google.com/apis/design/resource_names) for the appropriate value for this field. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for `SetIamPolicy` method.
  &quot;policy&quot;: { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { &quot;bindings&quot;: [ { &quot;role&quot;: &quot;roles/resourcemanager.organizationAdmin&quot;, &quot;members&quot;: [ &quot;user:mike@example.com&quot;, &quot;group:admins@example.com&quot;, &quot;domain:google.com&quot;, &quot;serviceAccount:my-project-id@appspot.gserviceaccount.com&quot; ] }, { &quot;role&quot;: &quot;roles/resourcemanager.organizationViewer&quot;, &quot;members&quot;: [ &quot;user:eve@example.com&quot; ], &quot;condition&quot;: { &quot;title&quot;: &quot;expirable access&quot;, &quot;description&quot;: &quot;Does not grant access after Sep 2020&quot;, &quot;expression&quot;: &quot;request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;)&quot;, } } ], &quot;etag&quot;: &quot;BwWWja0YfJA=&quot;, &quot;version&quot;: 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;) etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/). # REQUIRED: The complete policy to be applied to the `resource`.

    { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { &quot;bindings&quot;: [ { &quot;role&quot;: &quot;roles/resourcemanager.organizationAdmin&quot;, &quot;members&quot;: [ &quot;user:mike@example.com&quot;, &quot;group:admins@example.com&quot;, &quot;domain:google.com&quot;, &quot;serviceAccount:my-project-id@appspot.gserviceaccount.com&quot; ] }, { &quot;role&quot;: &quot;roles/resourcemanager.organizationViewer&quot;, &quot;members&quot;: [ &quot;user:eve@example.com&quot; ], &quot;condition&quot;: { &quot;title&quot;: &quot;expirable access&quot;, &quot;description&quot;: &quot;Does not grant access after Sep 2020&quot;, &quot;expression&quot;: &quot;request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;)&quot;, } } ], &quot;etag&quot;: &quot;BwWWja0YfJA=&quot;, &quot;version&quot;: 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time &lt; timestamp(&#x27;2020-10-01T00:00:00.000Z&#x27;) etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).

Each occurrence of a principal counts towards these limits.
